Must you identify yourself to police in New York?

CPL § 140.50(1) is New York's codification of the street stop, and it is written more narrowly than the federal Terry standard it grew out of. Three limits sit in the first sentence. The officer must be a police officer acting in a public place located within the geographical area of that officer's employment, so a stop by an officer outside that territory is not authorized by this section. The officer must reasonably suspect that the person is committing, has committed or is about to commit either a felony or a misdemeanor defined in the penal law. That second clause matters in practice: a suspected violation, a traffic infraction, or an offense created only by a local ordinance or by another chapter of the consolidated laws does not trigger § 140.50 authority on its face. Subdivision 2 extends the identical power to peace officers who provide security services for a court of the unified court system, but only in or about the courthouse to which the officer is assigned.

What the officer may then do is spelled out as a demand for three specific things: "his name, address and an explanation of his conduct". Nothing in Article 140 makes a refusal an offense, sets a fine, or authorizes an arrest for silence alone. That is the whole answer to the question most New Yorkers are actually asking. Refusal is also not, by itself, obstruction. Penal Law § 195.05, obstructing governmental administration in the second degree, requires that the person intentionally obstruct, impair or pervert the administration of law by means of intimidation, physical force or interference, or by means of any independently unlawful act. It is a class A misdemeanor, and the statute's own text requires conduct beyond declining to speak.

The frisk is a separate step with its own trigger. Under § 140.50(3) the officer may search the stopped person only when, having stopped them under subdivision 1 or 2, the officer reasonably suspects that he is in danger of physical injury. The search is limited by object, not by convenience: a deadly weapon, or an instrument, article or substance readily capable of causing serious physical injury and of a sort not ordinarily carried in public places by law-abiding persons. If the officer takes something, subdivision 3 requires that at the completion of the questioning the item be returned if lawfully possessed, or the person arrested. There is no third option in the text under which the officer simply keeps a lawfully held item.

Giving a false name is where New York does impose criminal liability. Penal Law § 190.23 defines false personation as knowingly misrepresenting your actual name, date of birth or address to a police officer or peace officer with intent to prevent that officer from ascertaining the information, and it builds a warning into the elements: the misrepresentation is only criminal "after being informed of the consequences of such act". False personation is a class B misdemeanor, which under Penal Law § 70.15(2) carries a definite jail term fixed by the court not exceeding three months, and under Penal Law § 80.05(2) a fine not exceeding five hundred dollars.

Behind the wheel the calculus changes. Vehicle and Traffic Law § 507(2) provides that failure by a licensee to exhibit a license valid for operation to a magistrate, motor vehicle license examiner, motor vehicle investigator, peace officer acting pursuant to his special duties, or police officer is presumptive evidence that he is not duly licensed. New York's drafting choice here is evidentiary rather than punitive: not producing the license does not create a standalone refusal offense, it shifts the proof burden on the unlicensed-operation charge.

One subdivision applies only to New York City. Section 140.50(4) reaches "cities with a population of one million or more", and New York City is the only municipality in the state that clears that threshold. In those cities, information establishing the personal identity of someone stopped, questioned and/or frisked, such as name, address or social security number, may not be recorded in a computerized or electronic database if the individual is released without further legal action. The same subdivision expressly preserves the recording of generic characteristics such as race and gender. Outside New York City this database restriction does not apply, which is why the answer to "what happens to my information" differs depending on which side of the city line the stop occurs on.

50 demand carries no statutory penalty in New York, and the section contains no arrest authority for it. 05(2). 05, a class A misdemeanor. A driver who cannot exhibit a valid license faces the § 507(2) presumption that he is not duly licensed, which supports an unlicensed-operation charge rather than a separate refusal charge. 50(3).
